For years, most parcel shippers have worked within a familiar carrier mix: UPS, FedEx, and USPS. Depending on the shipment, one carrier might offer the better rate, another might have the stronger service, and a third might make more sense for a particular zone or package profile.
Amazon is making that decision more complicated.
Amazon Shipping has been expanding beyond its original role as a delivery option for Amazon sellers, giving businesses another carrier to consider for orders fulfilled through their own operations. At the same time, Amazon continues to expand the logistics infrastructure behind its massive ecommerce operation.
That puts a new question on the table for shippers: Does Amazon Shipping deserve a larger share of the parcel volume currently going to UPS, FedEx, or USPS?
For some businesses, the answer may be yes. For others, the savings may not justify changing their current carrier strategy.
The important part is having enough data to know the difference.
What Is Amazon Shipping?
Amazon Shipping is a parcel delivery service that allows businesses to use Amazon's transportation network to deliver orders, including orders placed through sales channels outside Amazon.
That makes it fundamentally different from two other Amazon logistics services that are often lumped together with it.
Fulfillment by Amazon (FBA) is a fulfillment service. Businesses send inventory to Amazon, and Amazon handles storage, picking, packing, shipping, returns, and related customer service.
Amazon Logistics, meanwhile, is Amazon's delivery operation for Amazon's own orders. It encompasses the last-mile infrastructure Amazon has developed to get packages from its fulfillment and delivery network to customers.
Amazon Shipping is the carrier service. It is the piece that belongs in the same carrier evaluation as UPS, FedEx, and USPS.
That distinction matters. A shipper considering Amazon Shipping does not necessarily need to change its warehouse or fulfillment operation. It can continue fulfilling orders itself while using Amazon as another transportation provider.
Why Amazon Shipping Is Getting More Attention
Amazon already has something most new carriers would spend decades trying to build: enormous parcel volume.
Amazon's ecommerce business is supported by its:
Fulfillment centers
Sortation facilities
Delivery stations
Transportation network
Last-mile delivery operation
Amazon is now looking for ways to put more of that infrastructure to work for outside businesses.
The company's recent Amazon shipping changes have made that strategy more relevant to businesses that may never have considered Amazon a conventional carrier.
In 2026, Amazon expanded Amazon Supply Chain Services to businesses of all sizes, opening access to capabilities across fulfillment, transportation, distribution, and parcel shipping. That is a meaningful development for shippers because it signals that Amazon is not simply trying to offer another shipping label. It is increasingly positioning its logistics network as infrastructure that other businesses can use.
That creates competition for UPS, FedEx, and USPS.
It also creates an opportunity for shippers.
Amazon Shipping vs. UPS and FedEx
The question behind any Amazon Shipping vs UPS or Amazon Shipping vs FedEx comparison should not be, "Which carrier has the lower published rate?"
That is too simplistic for parcel shipping.
A shipper's actual transportation cost depends on the shipment profile and the terms surrounding it. Final invoices are effected by:
Weight
Dimensions
Zone
Service level
Residential status
Fuel
Additional handling
Delivery area charges
Minimums
Other accessorials
A carrier that looks cheaper on a rate card can therefore become more expensive once the entire shipment is priced.
The same applies to Amazon.
Amazon Shipping may be highly competitive for certain shipment profiles, destinations, or delivery requirements. That does not mean it will be the best option across an entire network.
This is why shippers should evaluate Amazon against their own UPS, FedEx, and USPS data, rather than relying on a generic carrier comparison.
Amazon Shipping vs. USPS: Another Different Equation
USPS can be particularly competitive for certain residential and lightweight shipments, while UPS and FedEx have extensive commercial parcel networks and negotiated pricing structures.
Amazon introduces another set of economics.
Its network was built around high-volume ecommerce deliveries, which can make its operating model particularly interesting for businesses with similar shipment characteristics.
A shipper with a high concentration of certain residential zones may see a very different result from a shipper with predominantly commercial deliveries. A business shipping lightweight parcels will have different economics from one sending larger or more complex packages.
The carrier decision has to account for those differences.
Don't Ask Which Carrier Is Cheapest. Ask Where Each Carrier Is Cheapest.
This is where carrier diversification becomes useful.
The goal does not have to be replacing UPS with Amazon, or FedEx with Amazon.
It may simply be moving the right shipments to the right carrier.
A shipper might find that:
Amazon is competitive for a particular group of ground shipments.
UPS remains the better option for specific commercial lanes.
FedEx performs better for another service or destination profile.
USPS continues to make sense for lightweight residential packages.
That could be a more realistic carrier strategy than choosing one provider as the winner for some.
It is also why managing parcel spend across multiple carriers requires more than keeping a spreadsheet of negotiated rates. As discussed in Lojistic's guide to parcel spend management, carrier diversification can create savings opportunities while also making contracts, surcharges, billing, and performance more difficult to manage.
What Should You Look At Before Moving Volume?
Start with your actual shipments.
A useful carrier analysis should show how much you're spending today and what is driving that spend. At a minimum, look at:
Origin and destination
Zone
Weight and dimensions
Service level
Residential versus commercial delivery
Base transportation charges
Fuel and accessorial charges
Contractual discounts
Cost per shipment
Delivery performance
Then model what happens if Amazon takes a portion of that volume.
This is where shipping cost comparison becomes much more useful than simply looking at carrier rate sheets. You can evaluate the economics of different carriers against the shipments you actually tender.
That distinction is important.
The question isn't whether Amazon Shipping is cheap.
The question is whether Amazon Shipping is cheaper for the shipments you are currently sending through another carrier.
Amazon Could Also Change Your Negotiating Position
There is another reason to evaluate Amazon even if you don't intend to move a large percentage of your volume.
A credible alternative carrier gives shippers another point of leverage.
If UPS, FedEx, USPS, and Amazon are all competing for portions of the same volume, procurement teams have more options when negotiating rates and contracts.
But that leverage only works if you know what the alternatives are actually worth.
That requires accurate data, not assumptions.
Lojistic's shipping analytics software gives shippers visibility into carrier spend, while carrier connectors bring carrier data together for analysis. With that information in one place, teams can evaluate their current network and identify where a carrier change could produce actual savings.
Model the Scenario Before You Move the Volume
This is where a carrier RFP should go beyond asking carriers to submit rates.
Suppose Amazon Shipping comes back with an attractive proposal. The next question shouldn't be, "How much lower are these rates?"
It should be, "What happens to our total transportation spend if we move 10%, 25%, 40%, or all of our volume?"
That means modeling the proposed rates against historical shipments and accounting for the factors that actually affect invoice cost.
Lojistic's rate optimization and RFP capabilities help shippers evaluate carrier pricing against their existing transportation data. That allows businesses to model different carrier scenarios before making a volume commitment.
The same analysis can be used when negotiating with an incumbent.
If Amazon can take a portion of the network at a lower total cost, that information can inform the next UPS or FedEx negotiation. If Amazon is not competitive for a particular segment, there is no reason to move that volume simply because it is a new option.
Watch What Happens After the Switch
Carrier analysis should not stop when a new contract is signed.
Actual invoices need to be compared with expectations.
A new carrier can look attractive during an RFP and produce a very different result once real shipments start moving. Changes in shipment characteristics, surcharges, service usage, and billing can all affect the savings originally projected.
That makes ongoing shipping reporting important after a carrier change. It gives transportation and finance teams a way to see whether the expected savings are actually showing up in the data.
It also helps identify when the carrier mix needs to change again.
Parcel networks are not static. Neither are carrier pricing strategies.
Amazon Shipping Changes Make Carrier Visibility More Important
Amazon does not need to replace UPS, FedEx, or USPS to change the parcel market.
If it becomes a viable option for even a portion of a shipper's volume, it changes the conversation around carrier selection, pricing, and capacity.
That makes the Amazon shipping changes worth watching even for businesses that have no immediate plans to use Amazon Shipping.
The companies best positioned to respond will be the ones that already understand their carrier economics.
They know where their volume is going, what each shipment actually costs, which surcharges are driving spend, how contracts are performing, and where another carrier could realistically improve the network.
That is a much stronger position than reacting to a new carrier after the fact.
Use Your Shipping Data to Make the Carrier Decision
Lojistic brings carrier shipment and invoice data together so businesses can see what they're spending, what is driving that spend, how carriers are performing, and where opportunities exist.
A free Lojistic account includes carrier analytics, reporting, carrier connections, and Compare Mode for measuring the impact of operational and carrier changes. Lojistic's rate optimization support also includes contract analysis, RFP support, re-rating studies, and scenario modeling to quantify proposed carrier pricing against actual shipping data.
So if Amazon Shipping gives you another option, don't guess whether you should use it. Run the shipments, model the scenarios, understand the contract impact, and then give each carrier the volume it earns.

Frequently Asked Questions
Not as a complete one-for-one replacement for many shippers today. Amazon Shipping is primarily a 2–5 day U.S. ground parcel service, while UPS and FedEx provide much broader expedited, air, international, and specialized transportation services. Amazon can, however, replace a meaningful portion of ground volume for the right shipping profile.
In some cases it can be wildly more competitive, but there is no universal answer. Amazon currently offers no additional residential surcharge or weekend delivery fee, and industry experts have reported aggressive Amazon pricing on some residential ecommerce shipments. Actual savings depend on package characteristics, zones, service requirements, existing carrier discounts, Amazon's proposal, and how moving volume affects incumbent carrier incentives.
Amazon says its transportation network operates seven days a week and offers 2–5 day ground delivery across the contiguous United States. Pickup availability varies by location and shipper volume, so businesses should confirm service from each origin facility.
Amazon says it works with USPS to deliver to certain destinations including P.O. boxes and remote locations.
Amazon's standard U.S. Amazon Shipping service is focused on the 48 contiguous states. Its published shipping zones exclude Alaska, Hawaii, Puerto Rico, and U.S. territories.
FBA is a fulfillment service in which Amazon stores inventory and handles activities such as picking, packing, and fulfillment. Amazon Shipping is a transportation service. A business can fulfill orders from its own facilities and use Amazon Shipping solely to transport packages to customers.
Generally, that isn't the right starting point. The better approach is to identify which shipments Amazon can serve competitively, model the effect of moving those shipments, account for changes to existing carrier agreements, and build the carrier mix that produces the best combination of cost and service.
